Mobrey Displacer Level Switches: Precision Liquid Level Monitoring in South Africa
When precision and durability are required in process industries, Mobrey mechanical level switches offer industry-proven performance. At Blanes Pressure Solutions, a trusted distributor of Mobrey in South Africa, we supply both vertical and horizontal displacer level switches, as well as HART-enabled models, built to handle challenging process environments.
What is a Displacer Level Switch?
A displacer level switch detects the presence of liquid based on buoyancy force acting on a spring-suspended displacer. As the liquid level rises or falls, the change in force triggers a mechanical switch — a reliable method for level control, pump activation, alarms, or trips.
Mobrey switches are known for their rugged mechanical construction, making them ideal for critical industrial applications.
✅ Mobrey Displacer Switch Configurations
1. Vertical Displacer Level Switch
-
Mounted from the top of tanks or vessels.
-
Supports multi-point level detection with multiple displacers.
-
Performs well in deep tanks, including those with chemical or corrosive contents.
2. Horizontal Displacer Level Switch
-
Mounted from the side of the tank, offering a compact and direct installation.
-
Perfect for point-level monitoring where top access is limited.
-
Ideal for feedwater tanks, boilers, and horizontal vessels.
HART-Enabled Mobrey Switches for Smart Control
Upgrade your process plant with Mobrey displacer level switches that support HART communication. These models offer 4–20 mA analog signals with a digital overlay for remote diagnostics and configuration.
Benefits of HART-Enabled Switches:
-
Remote setup and monitoring via DCS or handheld communicator.
-
Improved plant safety and predictive maintenance.
